These Chevrolet Performance valve stem seals control the lubrication of the valve stem as it slides into the valve guide. Too little oil contributes to stem and guide wear, and too much oil increases oil consumption and can cause a buildup of carbon. This leads to valve seat damage and early valve failure, as well as reduced engine performance and emission failures. These Chevrolet Performance valve stem seals ensure dependable performance and superior service life.
